What's New in MRIcontrast

2.1

February 4, 2021

- The gradient echo protocol now has RF-spoiling which can be turned on and off. - A new steady-state free precession (SSFP-Echo) protocol has been added. - All major types of gradient echo sequences can now be simulated. - All protocols (sequences) now obey timing limitations set by the MRI scanner hardware (finite RF-pulse durations, gradient switching times, etc). - Minor user interface enhancements. - Bug fixes.

No abdominal region, no transverse section of brain as it’s shown in the image

Nope.. not the app you want to invest in

Response from developer

Hello Alex, You are right that there is no sagittal brain image (yet), but there is one planned for the coming 1-2 months, as well as a pelvic image. Be aware that the purpose of the app never was to be an anatomical atlas, there are numerous other apps and sites that do that much better, but rather to be an app where the user can explore how different MRI scan parameters impact the image, not only in terms of image contrast, but also in terms of noise and image artifacts. We believe this purpose is achieved also with a limited number of anatomies, although we had wished for many dozens of different types of images. Kind regards SMRI Consulting

Way too much money

Not worth the price, but the images are nice. Would be helpful to give some information about the techniques and what they are good for. Overall, I would not recommend this. What you see in the sample images is all you get

Response from developer

From version 1.2, a detailed description of every imaging protocol is available, including descriptions of all changeable parameters. Regarding the images, please note that they are not static. The purpose of the app is to allow the user to change every imaging parameter and instantly see how the appearance of the image changes. This is unique, one-of-kind feature. To enter edit mode, just tap any image in the collection of imaging protocols.

Good educational tool

This is a good tool for MR radiographer and students learning basic sequence and tissue contrast.

FAQ

What is MRIcontrast?

MRIcontrast is an interactive simulator designed for healthcare professionals to learn how magnetic resonance imaging (MRI) scan parameters affect MR images. It allows users to visualize realistic MRI images and adjust settings in real-time.

Who is MRIcontrast for?

This app is specifically designed for healthcare professionals working with MRI, including radiologists, technologists, and students, who want to deepen their understanding of MRI physics and image acquisition.

What scan parameters can be adjusted in MRIcontrast?

Users can adjust parameters such as repetition time (TR), echo time (TE), flip angle, magnetic field strength (1.5T or 3T), and many others. Changes are reflected immediately in the MR image.

Does MRIcontrast offer guidance for beginners?

Yes, MRIcontrast includes a built-in tutorial that explains the meaning of each parameter and its effect on the MR image. It also provides detailed explanations of imaging protocols and guides for exploration.

What types of MRI sequences are included in MRIcontrast?

The app features a gallery of common sequence types, including T1-, T2-, and PD-weighted spin echo, T2*-weighted gradient echo, steady-state free precession (SSFP), balanced SSFP, inversion recovery, turbo spin echo, and echo planar imaging (EPI).

How much does MRIcontrast cost?

MRIcontrast is a paid application, available for $14.99. It does not appear to have any in-app purchases or subscription models.

On which devices can I use MRIcontrast?

MRIcontrast is supported on iPhone, iPad, and iPod devices. It is rated for ages 4 and up.
